Updating Image of a Tkinter Label
To update image in a Label, an event has to happen. A button is created and on clicking the button, the image in the Label gets updated to another image. A function is assigned to the ‘command’ option of the Button widget to update the image of the Label at a button click. Two images are needed, where one image is initially displayed in the Label widget, and the another image is updated in the Label on clicking the button.
# importing tkinter
import tkinter as tk
# Function to update the image in label
def update_image_in_label():
label_pic.config(image=image_2)
# tkinter application window
root = tk.Tk()
root.title("w3wiki")
root.geometry("400x200")
root.config(bg="green")
# Converting image to PhotoImage variables
image_1 = tk.PhotoImage(file="books_picture.png").subsample(2, 2)
image_2 = tk.PhotoImage(file="w3wiki-logo.png")
# Label widget with image
label_pic = tk.Label(root, image=image_1)
label_pic.pack(pady=15)
# Button widget
update_button = tk.Button(root, text="Update image",
command=update_image_in_label,
bg="black", fg="white",
font=("Arial", 15))
update_button.pack()
# Run application
root.mainloop()
Output:
